Re: Is time trialling to be banned on dual carriageways (A63)

Personally, I would not at all be negatively affected if cycling were banned on all 70 mph dual carriageways, since I would never cycle on this kind of road. Such a ban could possibly even be a good thing. Some years ago, cycling was banned on the A90 just outside Edinburgh. The alternative path was...

Re: Dynamo system choices

What about a 1.5W bottle dynamo? If 3W gives an adequate amount of light for town riding using incandescent bulbs, surely 1.5W ought to be more than enough for town riding with LEDs. I know that 1.5W hub dynamos exist, but I haven't heard of a 1.5W bottle dynamo. I agree that the noise of a bottle d...

Re: Which chain Guard?

Hello Belgiangoth I have this chain case: https://www.dutchbikebits.com/mudguards-chainguards-fenders-coatprotectors/chainguards/hesling-original-chaincase I find it very worthwhile. When I look at the places where it is dirty, not all of them are in areas which would be covered by a hockey-stick ch...

Re: Why are recumbents so rare?

I have a Dutch friend who owns a Zephyr Lowracer. Yesterday I asked him why he didn't bring it with him when he moved to the UK. He replied: "Because I want to live!" This friend rides an upright to work every day here. He also commented that even in the Netherlands he has some safety conc...

Re: Why are recumbents so rare?

Hello Tangled Metal I bought a very good second hand recumbent for a good price in a village a few miles away from me. (It was on ebay). I'm not in London or SE. If you keep your eyes peeled, hopefully something will turn up locally. Some recumbents have racks for conventional panniers. Others use s...

Re: Why are recumbents so rare?

Hello all I suppose I was really making two points: 1. People won't ride recumbents if they perceive them to be dangerous in traffic. 2. As enthusiasts, we shouldn't misunderstand what most people want from a bike. Personally I find the experience of riding in busy traffic more unpleasant on the rec...

Re: Fast rolling tires? 26 inch

Schwalbe Kojaks are described by many people as being quite fast. But on bicyclerollingresistance.com they get a very poor rating. What's going on? Are people being deceived by their perceptions? (more vibration=faster) Are the bicyclerollingresistance.com tests simply wrong? Do the bicyclerollingre...

Re: Why are recumbents so rare?

I do think that the presence of busy motor traffic has a big influence on who cycles, where they cycle, and what kind of bike they ride. If people perceive riding a recumbent in traffic to be too dangerous they won't do it, even if there is no hard evidence for this. (We on this forum think it's fin...

Re: Recumbent Steering - What's going on?

I can ride no-hands on my Metabike, but I need to be going quite a bit faster than on an upright and it takes a lot of concentration.

Initially I found "superman" type handlebars much more intuitive and similar to an upright bike. However, with a bit of practice tiller bars are also fine.

Re: Avoiding power idler by using Alfine hub gear

Hi all I realised that the boom had been cut down by a previous owner. Because I am quite tall, I have the boom extended fairly far out. This meant that not enough of the boom was inside the frame, causing undue flex. I was able to buy a spare full length boom from someone on BROL, and this has fixe...

Re: You can forget about your Dutch-style cycling facilities

Here is an interesting blog post about Stevenage, written by someone who designs roads for a living and has done a bit of cycling in the Netherlands.

Re: Avoiding power idler by using Alfine hub gear

Hello all Thanks for the interesting responses. I'll reply to a few points, and then add some new thoughts. Replies [XAP]Bob: I was thinking of vertical bending, rather than horizontal bending or torsion. I'm much more aware of vertical movement than the other two, although I'm sure they do happen t...

Re: Cycling as a whole; losing the plot...?

This is a slightly different angle to Brucey's original point, but perhaps part of the reason this "progress" is frustrating, is that so much effort is going on things which are relatively unimportant (e.g. adding another sprocket), when there are other areas with significant potential for...

Re: Avoiding power idler by using Alfine hub gear

Thanks for the replies. Hercule: Yes the range of the 11 speed Alfine is a bit less than I had thought. Or rather, my current gear range is a bit more than I thought. I use all the gears I have. UpWrong: I found an old thread on BROL, where someone from Bacchetta was suggesting losses of 1-2% for an...

Avoiding power idler by using Alfine hub gear

Hello all I have a Metabike, which I enjoy riding. It currently has 3*10 derailleur gears. The idler is quite noisy, because it only bends the chain through a small angle. I have discovered that it is possible to remove the idler and ride the bike like that. Unfortunately in some of the gears the ch...
